The invention relates to a preparation process of honeysuckle tea. The preparation process comprises six steps of raw material collection, spreading for water removal, steaming for water removal, water removal with a roller, rolling for shaping, and baking for flavoring. The preparation process combines the three water removal ways, and can effectively remove green smell of fresh honeysuckle leaves and simultaneously promote aromatic substances to volatile, so that the honeysuckle tea leaves obtained from water removal are fresh and green in color, aromatic in smell, and free from burnt edges and burnt tips; and during the steaming for water removal, the green smell of the honeysuckle is promoted to discharge at a certain temperature and under certain pressure in a stewing process, the green smell is discharged out of a steam water remover through vacuumizing, the honeysuckle is under a negative pressure state due to vacuumizing, and then steam is filled in a circulating way to pressurize so as to completely discharge the green smell of the honeysuckle and to promote the aromatic substances of the honeysuckle to volatile at the same time. The honeysuckle tea prepared by the process not only has remarkable functions of clearing away heat and toxic materials, eliminating inflammation, sterilizing, relieving summer heat and restlessness, reducing blood pressure and the like, but also has a significant effect in low-temperature preparation; and meanwhile, the honeysuckle tea is sweet in mouthfeel, fresh in color, aromatic and intense in tea flavor, and easy to be popular in people.
